小编bl4*_*ird的帖子

我再次,现在有一个spring-boot-starter-data-jpa问题.我使用spring-boot来访问多个数据库.MongoDB是正确的,也是Cassandra,最后一个PostgreSQL和JPA有一些问题.我认为我的配置可能有误.你能帮我解决一下吗？我使用了spring-boot,spring-data-jpa引用和spring-boot-starter-data-jpa引用.什么都没有帮助.我发现一些线程在stakeoverflow,使用jdbc与hsql依赖,因为jpa将无法正常工作链接.我自己尝试了这个,但是我得到了一个没有合格的bean错误.

所以我退后一步,包括jpa和hsql,写一个PostgresConfig类没有任何帮助.如果我使用@EnableJpaRepositories Annotation,我会收到有线错误.请参阅Stacktrace Para 67.5.2错误...我没有使用这个liquibase thingy,idk为什么会出现错误...否则,如果我不使用DataSourceBuilder,我的application.properties将无法读取,我得到了数据库键入NONE错误.
